Excerpt from A Manual of Physical MeasurementsThe cmnputation of results should gmnerallv be done at home. And the complete experiment recorded in a sepa rate note book to be handed to the instructor as the final report upon the work of the course. In this book the date, number, name and object of the exercise should precede the record of observations and the computed results. This material together with any necessary explanatory memo randa should be written on the right howl page, the left hand page being reserved. For sketches of apparatus, and the de rivation of necessary formulae. Separate page should always be begun for each new experiment.Graphical Methods. It is frequently of interest to verify a law stating the relation that is known to exist be tween two quantities, or to detect and determine such a re lation where it is not known.
